WARNING: One or more of your mailservers |
|
|
I'm running a test through www.dnsstuff.com and get the following issues.
I don't see much for help on the internet, but I gather some of these are
meaningless.
Which of these need to be fixed and how do I fix them?
1) ERROR: I checked with your nameservers to see if there were any CNAMEs
for your NS records (there shouldn't be), but they all timed out.
2) WARNING: One or more of your mailservers may be claiming to be a host
other than what it really is (the SMTP greeting should be a 3-digit code,
followed by a space or a dash, then the host name). This probably won't
cause any harm, but may be a technical violation of RFC821 4.3 (and RFC2821
4.3.1).
3) Your domain does not have an SPF record. This means that spammers can
easily send out E-mail that looks like it came from your domain, which can
make your domain look bad (if the recipient thinks you really sent it), and
can cost you money (when people complain to you, rather than the spammer).
You may want to add an SPF record ASAP, as 01 Oct 2004 was the target date
for domains to have SPF records in place (Hotmail, for example, started
checking SPF records on 01 Oct 2004).
thanks! |

Do you have NS records and matching "A" records for the name server name?

Here is an example, your MX record points to "mail.domain.com" but your mail
server answers with just "mail" in its greeting.

Go to spf.pobox.com run the wizard and paste the results of the wizard to a
(same as parent folder) txt record in you domain.
Mail servers that check SPF will look at the record, to see it any mail
claiming to be from your domain is coming from the mail servers or IPs
listed in the SPF record.
Post your actual domain name if you want it checked further.
